Question

Factor 3h2 – 11h – 42 completely

Answer 1

The answer is H= (-3, -0)

Answer 2

The expression if factorized completely to give (3h + 7)(h - 6)

From the information given, we have that the expression is;

3h² - 11h - 42

Now, find the product of the coefficient of h² and the constant value that sums up to give - 11, then, we have;

3h² -18h + 7h - 42

Now, group the expression in pairs, we have;

(3h²- 18h) + (7h - 42)

factor out the common terms, we have;

3h(h - 6) + 7(h - 6)

Now, we get that;

(3h + 7)(h - 6)
